[JBoss-user] [Clustering/JBoss] - Cluster error: failed to replicate session

We had a melt-down on our production JBoss cluster this morning. The errors being logged (1000s of times) were this: anonymous wrote : | 2006-03-15 07:31:41,612 ERROR [org.jboss.cache.lock.IdentityLock] write lock for /JSESSION/localhost/sunOLM2/hxCHnkvAh4ZboOrlmGqzSg** could not be acquire

[JBoss-user] [Clustering/JBoss] - Re: Http Session replication problems when NOT using sticky-

After some very careful testing of whether invalidate() and removeAttribute() are successfully replicated to cluster nodes other than the one where they were executed, we found that this reliably didn't work in a non-sticky-session configuration. The same tests worked correctly when we converted

[JBoss-user] [Clustering/JBoss] - Re: Http Session replication problems when NOT using sticky-

I'm sure that the scenario you describe will work, but the whole point of this thread is that I'm trying to make the cluster work when it's not using sticky-session. Is thre any way I can push the removeAttribute or invalidate to the other node without shutting down? View the original post : h

[JBoss-user] [Clustering/JBoss] - Re: Http Session replication problems when NOT using sticky-

I just found a parameter in jbossweb-tomcat55.sar/META-INF/jboss-service.xml which looked as though it should fix my problems: | | true | This looked like it should solve my problems, but I changed the value to "false" and it didn't make any difference :-( John View the or

[JBoss-user] [Clustering/JBoss] - Re: Http Session replication problems when NOT using sticky-

My test application uses struts, but the session attribute I'm using as a marker is not used by struts. I have 2 JSP pages. Each displays the name of the host that served it, and then lists the name/value of all session attributes, like so: | <% | java.util.Enumeration enm = session.get

[JBoss-user] [Clustering/JBoss] - Re: Http Session replication problems when NOT using sticky-

I now have a simple test application which reliably shows that if I attempt to remove either a session (using HttpSession.invalidate()) or a session attribute (using HttpSession.removeAttribute(String)), the change is not immediately made on the remote cluster node. I am testing to find out how

[JBoss-user] [Clustering/JBoss] - Re: Http Session replication problems when NOT using sticky-

We are trying to avoid using sticky-session because that would mean that we also have to use it on the two hardware load-ballancers in front of the cluster and web servers. The Operations group doesn't want to make this change... Replication-granularity is set in the jboss-web.xml file and we're

[JBoss-user] [Clustering/JBoss] - Http Session replication problems when NOT using sticky-sess

I have a JBoss cluster, v4.0.3, with two nodes. Load balancing uses mod_jk, but without sticky-session. I am having problems when a session is invalidated and then a new set of attributes set in a new session (i.e. someone logs out, then logs in again as a different user). HttpSession sess =

[JBoss-user] [JBossCache] - Re: Message discarded from non-member

I've seen this problem, caused by having another JBoss machine on the same network, using the same mcast address and port, but a different partition name. Remember also that the "all" configuration creates two cluster partitions, one defined in cluster-service.xml, the other in tc5-cluster-servi

[JBoss-user] [Clustering/JBoss] - Farm not replicating an updated WAR file

I am running a JBoss cluster with 2 members, running JBoss 4.0.2. and JDK 1.4.2_09 The configuration is very close to the "all" configuration in the standard distribution. I am having intermittent problems where a WAR file deployed in the "farm" directory on one cluster member is not being copi

[JBoss-user] [Clustering/JBoss] - Re: Do different Cluster Partitions need different multicast

That explains what we've been seeing, and may explain some unreliability with replication of deployments made to the farm directory. I'll make the changes and start testing again Thanks! John View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3899136#3899136 Re

[JBoss-user] [Clustering/JBoss] - Do different Cluster Partitions need different multicast IP

I am running several JBoss 4.0.2 clusters on the same sub-net. Only HttpSession is clustered. The cluster membership is set using -Djboss.partition.name=foo when I start JBoss. My problem is that although the clusters have different names, it seems that every server is part of the same partiti
